Application filed January is, 1912. Serial No. 671,350.

To all whom it may concern:

Be it known that I, Gsoncn E. Smrrro, a citizen of the United States of America residing at Cleveland, in the county oi Cnyahoga and Stateof Ohio, have'invented certain new and useful Improvements in Percolators; and I herebydeclare the fol-,

lowing to he a. full, clea-r. and exact clescrip hon of the invention, such as will enable others skilled in the art to which itpertains to make and use the same.

This invention relates to improvements in percolators for extracting oil or grease from ease-yielding material bv the treatment oi said material with 'a solvent, such, for instance. as naphtha.

The primary obijectpf this invention is to produce a perco ator comprising a pivotally supported dumpin receptacle arranged to be swung or rotated in a'vertical plane andprovidcd at the top with a. month adapted in the'normal position of the receptacle to'receivc the material to be treated} \Vltlllll.;tll8 receptacle and arranged to he brought intoa downwardly dischargi position during the swinging or rotation o the receptacle.

Another object is to have said ieceptaclearranged to dump into' a pit which forms a passagewayalong which the material" dumped by said receptacle is to be conveyed, and to'have .the mouth-of said receptacle project into said pit. dug-in" thc'dumping of material by the receptachi, so that none of the material to be discharged from the receptaclc is sputtered externally of the pit but allof said material is dumped into the pit, and the material received hv the pit from the receptacle is distributed by the receptzicle longitudinally of the pit, thereby avoidin obstructing the free discharge of material from the rece )tacle nnd facilitat- 'ing the conveyin of t 1e damped material along the pit to t it: place desired.

Another object isto permit dumping of means employed for supplying solvent-to the receptacle atthe top of the receptacle,

with the means employed for supplying steam to the neccptaclc at the bottom of the receptacle, with the means en'iployed for conducting vapor from the receptacle at the top of the'reccptaele, and with the means Another object is not only to provide a cor-er for the mouth of the receptacle. but to have said. cover carried by a vapor-conadl c'ting pipe'arranged to communicate with zszud mouth in themouth-closing position of the cover, and to have said pipe movable out of the way cpreparatory to the actuation of" the recepta e or dumping the contents of the receptacle.

Another object is torender a pcrcolator ofthe character indicated simple and durable in construction and reliable in its operatio'h.

With'these objects in' view, and to the end of realizing any other advantages here matter a pearmg,'this invention consistsin certain eatnres of construction, and comhinations and arrangement o'fparts, hereinafter described, pointed out in the claims, and illustrated in the accompanying; drawsaid drawings, l-igure 1 is an elevation, largely in section, of a percolator embody ing my invention. "Figs. 211ml 3 are horizontal sections on line'2-2, and line'*'3 3, respectively; Fig. 1, looking downwardly. Fig.4 is a vertical section on line 4-4. Fig. l, loolcin in the direction indicated hy the arrow. i '5 is a horizontal section on line 5-5, I ig. Llooking downwardly. Fig. '2 is drawn on a larger scale than Fig.1, and Figs. 3, and 5 are drawn on a larger scale than Fig.2. V i i Q neferring to Fig. .l of'said drawnnqm indicates a pit which forms a passageway along-which material dumped into the pit is conveyed in any approved nninner to'thc place desired, and two standards B and 13 are arranged above and at opposite sides respectively of said pit.

' My improved percolator comprises a dumping rece )tacle-C in which oil-yielding or rease-yiel in material (not shown) is to lie-treated wii h a solvenysuch. for instance, as naphtha. Said receptacle isrylindrical in cross-section. Said receptacle is supported from the. standards B. being pro vided externally and centrally between its upper and lower ends with two trumiints I) and E which are arranged horizontally ai opposite sides respectively of the receptacle and in line endwise, which trunnions have hearing in o posite smndards' respectively It will be o served therefore that the receptacle C is 'pivotally suppcrted trom the standards B and arranged to be swung or rotated in a vertical plane between the standards.

The receptacle C has a cortical top 10 (see Fig. ll and is provided centrally of said top with a mouth 1i. and G indicates a cover for closing said month. which cover is arranged above the receptacle and supported imlependently of the receptacle. as will hereinafter appear. and obviously any suitable means. such, for instance, as clamps (not shown) may be employed in tightly securing aid cover to the receptacle in the mouthclosing position of the cover. Fig. 1 shows the cover G in its mouth-closing position. The cover G is carried by a vapor-conducting pipe H which is provided with a valve 13. The pipe H is shown mounted in a bracket I which is pivoted vertically, as at 14, to a stationary beam J. The pipe H has a vertically arranged pivotal outer endportion [1 which projects downwardly and is provided at its lower or outer end (see Fig. ll with a collar 10 mounted on and suitably fixed to said pivotal portion of said pipe.

A stationary vapor-conducting pipe K, which (see Fig. l) is shown sup orted from a lianger L depending from an rigid with the beam J communicates (see Fig. 4) with the cover-carrying pipe H at the lower or outer end of the pivotal portion ll of said cover-carrying pipe and is provided with a stutling-box 17 which extends circumferen tially of said pivotal portion of said covercarrying pipe and has its annular packing 18 surrounding said portion of said cover-carrying pipe and confined between the gland :20 of said stutling-box and a ring 9.1 arranged at the inner end of the collar 16 and overlapping an upwardly facing shoulder 22 which is formed on and internally of the casing of slid stuffing-box. It will be observed that the projection of the collar 16 of the pivotal portion 11 of the cover-carrying pipe into the stufling-box 17 of the sta tionary pipe K insures the retention of so d pivotal portion of said cover-carrying pi .e internally of the packing of said stuflingbox. The axis of the bracket I and the axis of the pivotal portion ll of the pipe H are coincident to permit swinging of said pipe in a horizontal plane.

By the construction hereinbcfc-re described it will be observed that the vapor-conducting pipe H and the connected cover G are not only supported independently of the receptacle C but are swung in a horizontal plane during the actuation of the. bracket I in opening and in closing said cover. The pivotal portion llof the pipe H permits swinging of said pipe without interrupting communication between said )ipe and the stationary pipe K, and the stu jug-box comprising the packing 1S prevents leakage between said pipes. Of course the cover G is swung into an open position and out of the way preparatory to actuating the receptacle C for dumping material into the pit A.

The receptacle C (see Fig. 1) has a dishshaped bottom 22 and at the upper end of said bottom and internally is provided with a suitably constructed horizontally arranged screen which extends transversely of said receptacle and is secured in place in any approved manner and (see Figs. 1 and :2) consists of a vertically arranged metal ring 23 horizontally arranged bars 24 and plates 25 having perforations '26. The ring 23 rests on the bottom 22 and is secured in place in any approved manner. The bars ll-'are spaced laterally and extend transversely of the receptacle C. The perforated plates '25 rest on the ring 23 and on the bars Z-l to which one or more of said plates are bolted, as at 27, as shown in Fig. 2, and all of said plates are bolted, as at '28, to the ring The oilyielding or greaseyielding material to be treated in the receptacle C is fed into said receptacle at the mouth 12, ind the aforesaid screen forms a seat for a body of such material.

The trunnions D and E extend through the standards B, and the trunnion D (see Figs. 1 and 3) is operatively provided atits outer end with a worm-wheel 31 which has its axis coincident with the axis of the receptacle C and meshes with a rotary worm 3-2- which is supported from the standard affording bearing to said trunnion and conse quently independently of said receptacle, which worm is shown operatively provided with a driving-wheel 33 to which power is applied in any approved manner.--

Each trunnion of the receptacle C (see Figs. 1, 3 and 5) is provided interiorly with a bore 3-1 which extends longitudinally of the trunnion from within the inner end-portion to the outer extremity of the trunnion.

Lt the outer end of each trunnion is a tubular member 31 which is attached to and arranged in line endwise and rotates with said trunnion and communicates with the bore 34 in said trunnion. Adjacent the outer end of the tubular member M of the trunnion D is a stationary pipe-connection I. Adjacent the outer end of the tubular member M of the trunnion E is a stationary pipe connection Q. The pipe-connections P and Q comprise each a stationary tubular member 35 which is arranged in line endwise and communicates with the tubular member M of the adjacent trunnion. Each stationary tubular member 353 is provided at its free end and externally (see Figs. and 5) with a collar 36 mounted on and suitably fixed to said tubular member. The tubular member M of each trunnion is provided with a stuffing-box 37 which is rotatable with said trunnion and extends circumfcrentially of the tubular member 35 of the adjacent pipe- 4: j t at its vapoi'-receiving end with the bore 34 in said trunnion.-

connection, and the annular packing 38 of said stufiing-box surrounds said tubular member of said pipeconnection and is confined between the gland 40 of said stuiflug-bolt and a ring 41 which is arranged at the inner end of, the collar 36 projectin into said stalling-box and overlaps a shoulder 42 formed on and internally of the casing of said stutiin -box and facing in the direction of said pac ring, and it will be observed that the promotion into said smiling-box of the collar 36 of the tubular member 35 of saidv through the medium of said pipe-connection and t e tubular member M of the trunnion D, with the bore 34.- in said trunnion. The

steamipe 43 is provided with a valve 44.

A so vent-conducting pipe 45 (see Fig. 1) discharges into the pipe-connection? and is consequently placed in communication, throu h the medium ofsaid pipe-connection and s tubular member M of the trunnion D, with the bore '34 in said trunnion. The pipe 45 is provided with a valve 46 and connects with the. outlet of a suitably operated pump 47 whose inlet is connected with a pipe 48 for supplying a solvent, such, for instance, iiiil'nephthn. A

A liquid-conducting pipe 50 (see F ig. 1 has its liquid-receiving end connecting wit the pipe-connection 1 andthcrcforc placed in communication throu h the medium of said pipe-connection on the tubular member M of the trunnion D with the bore 34 iinthe said trunnion, Saidpipe 50 is provided with a. valve 51 end connects with theinlet of a suitably operated pump 52 which has its outlet discharging into a pipe,53 which leads to a reservoir (not shown).

A vapor-conducting pipe 54 (see Fig. 1)

Said pipe 54 and the pipe K are connected to a. pipe 0 in common, and the last-mentioned pipe leads to a condenser (not shown).

A liquid-conducting pipe. 56 (see Fig. l) connects at its liquid-receiving end with the pipe-connection Q and is consecpicutly placed in communication, through the medium oi said iipe-counect-ion and the tubular member 18 of the trunnion l), with the -bore 34 in suidtrunnion. The pipe 536 is provided with a valvp 57 and coniiccts =it.its discharging end Wllhhtl'le inlet of u suitably operated pump 58 w ich has its outlet dis-- charging into a pipe 59 which leads to a reservoir {not shown).

The receptacle-C (see Fig. 1) -is provided with u solvent-conducting pipe R which is arranged at the exterior of said receptacle and provided with a valve r. The p1 e R extends upwardly from the trunnion l to the top 10 of the receptacle and dischar es at said top into the upper portion of te rcwptacle. The pipe R-is attached at its Iowcrand solvent-receiving end to tho trunnion D and consequently arra ed at said 'cnd in proximity to the axis o the receptacle C. The pipe R communicates at its last-mentioned end with the bore {it-in the trunnion 1). Consequently sziidbore 34 in an id trunnion D and the valved pipe R form a valved passageway which discharges into the upper portion of the rece tacle C and has its receiving end arrang at the axis of solid receptacle, and opviously the solventsupp y-unnp48 mm) 7, i e45 l)B-00I1- nection P, and t he tiubuhii mcnib i M of said trunnion constitute ineuns whereby fluid may be supplied to said passageway at the'histvincntidncd end of the passageway.

The rcceptucle' C (see Fig. 1) is provided with a vaponconductiug pipe T which is arranged :it theexteriorjofsaid receptacle and provided with'u velvet; -The pipe '1 extends from the top 10 of the'receptacle C downwardly to the'trunnion and is at.- tached at its uppcr end tc'said top andthcre coniniunicntes with and forms "afvaporoutlct of said receptacle. The 'pipe T-is uttuched atits lower end to the, trunnion E.
